MECHANICAL MOVEMENT.

CPECFGLTION forming pari: of Letters Patent N0. 339,547, dated April 6, 1886.

Application tiled October Q6, 1885. Serial No. iE0,30. (No model.)

To afZZ whom it may concern..-

Beit known that I, CHARLEs HAMMELMANN, ofthe city of Buffalo, in the county ofErie and State of N ew York, have invented a new and useful Improvement in Mechanical Movements, of which the following is aspecification.

This invention relates to an improvement in that class of mechanical movements which are employed for converting the reciprocating' or oscillating motion ot' a hand-lever or treadle into a rapid rotary motion, and which are more especially employed for operating the rotary blowers of portable forges and other revolving instruments or devices which require a high rotary speed.

The object ot' myiuvention is to produce an efficient and compact mechanism of this kind which will produce the desired result in a very simple and direct manner, and my invention consists, to that end, of theimprovements which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, consisting of two sheets, Figure l is a side elevation of a portable forge provided with my improved mechanical movement. 4 Fig. 2 isahorizontal section, on an enlarged scale, through the'handle of the cliivi1ig-\;vlieel. Fig. 3 is a vertical section in lineman, Fig. 2. Fig. 4 is a vertical section in line y y, Fig. 3. Fig. 5 is a crosssection in lince z, Fig. 4. Fig. Gis a face view of the loose part of the clutch. Fig. 7 is a cross-section of the handlever support on an enlarged scale.

Like letters of reference refer to like parts in the several iigures.

A represents the bowl or hearth of a portable forge, supported on legs a, and provided with a hood, u. B represents the blower or fan, secured to the lower side of the bowl A, and provided with a suitable pulley on its shaft. All of these parts are constructed in Vany suitable or well-known manner.

G represents the driving wheel, connected with the pulley on the blower-shaft by an endless belt, c, andmounted loosely on an arbor, d, which is supported in the frame of the machine, and preferably made adjustable by setscrews cl', for tightening the belt c when required.

E represents ay cylindrical neck or collar ,provided with a neck, t'.

formed on one side of the hub of the wheel C, and F is a serrated or toothed clutch disk formed on or secured to the outer end of the neck E, with its toothed side turned toward the vwheel C. y

G represents a clutch-disk mounted loosely on the neck E, with the toothed side adjacent to the toothed side of the disk F. The latter is preferably cast in one piece with the neck E, and the disk G is made in two parts,which are secured together by screws g, after being applied to the neck E, as represented in Fig. 6. The teeth on the adjacent sides of the disks F and G are made inclined, so that upon turning the loose disk G forwardly in the direction of the arrow in Fig. 2 the motion of the loose disk will be transmit-ted to the disk F, while upon turning the loose disk in an opposite direction the disk E and the wheel O, secured thereto, will conti une their forward movement,

notwithstanding the reversal of the movement of the disk G.

h represents projecting lugs or ears formed on the periphery of the disk G.

H is a cylindrical collar or sleeve,wl1ich incloses the clutch-disks F and G, and which is The latter turns loosely on the arbory d, and is provided at its outer end with a gearpinion, J. The sleeve H is provided with inclined slots or ways j, in which the lugs h of the loose clutclndisk G engage, so that by turning the sleeve H forwardly the inclined slot-s j, acting upon the lugs 7L, will throw the loose disk G in engage ment with the disk F, and upon reversing the motion of the sleeve H the loose disk G will be moved out of engagement with the disk F. An alternating forward and backward rotary motion is imparted to the sleeve H by a vertical reciprocating rack-bar, K, which engages with the pinion J. The rack-bar is arranged in a casing, L, in which it is guided by vertical ribs l. The easing L is secured to the stationary frame of the machine by screws m, or in any other suitable manner.

N represents the pivoted hand-lever, which is connected with the rack-bar K by a rod, O. The latter is attached to the rack-bar and the hand-lever by eyes p 1;',Which permit of a suficient lateral movement of the hand-lever to allow the operator the requisite freedom of IOO movement for reaching tools, &c., while operating the blowerL The handlever N is pivoted by a horizontal bolt, q, to a bifurcated support, R, which in turn is pivoted to the supporting-standard S by a vertical bolt, s, as represented in Fig. 7, so that the hand-lever can be turned horizontally and vertically. Any other universal joint-for instance, a ball-and socket joint-may, however, be employed, if preferred.

Upon pressing the free end of the hand-lever downward, the rack-bar K is raised, and the pinion J and sleeve H are rotated forwardly in the direction of the arrow in Fig. 2, whereby the loose clutch-disk G is thrown in engagement with the disk F, and the latter `and the driving-wheel C are turned forwardly in the proper direction for operating the blower. On the reverse stroke of the hand-lever, the rackbar K descends, the pinion J and sleeve H are rotated in an opposite direction, the clutchdisk G is moved out of engagement with the disk F and turned in an oppositedirection, while the wheel C and connecting parts continue their forward rotation by the momentum imparted to the parts during the effective stroke of the hand-lever. In this manner the easy up-and-down motion of the hand-lever is converted into a rapid rotary motion of the driving-wheel'and blower, without requiring any counter-shafts or multiplying gears or pul leys. The blower or other rotating` part can only be rotated in the right direction', irrespective of the position of the handlever when the movement is begun, and the machine cannot stop at a dead-center, s0 that the machine is always ready to be set in motion by simply operating the liand-lever. By increasing or decreasing` the stroke of the liand-lever the speed of the blower is increased or decreased, and the hand-lever may at times be held stationary, with the clutch-disk G. disengaged from the disk F, without interfering with or arresting the rotary motion of the blower.

I claim as my invention- 1. The combina-tiomwitha driving-wheel, C, provided'with a clutch-disk, F, of a loose clutchdisk, G, which is turned alternately backwardl y and forwardly,and which is thrown in engagement with the disk F on its forward movement and out of engagement on its backward movement, substantially as set forth. l

2. The combination,with a drivin g-wheel, C, provided with a clutch-disk, F, of a loose clutchdisk, G, and a collar, H, which is turned alternately backwardly and forwardly, and which throws the disk G alternately in engagement and out of engagement with the disk F, substantially as set forth.

3. The combinatiomwitlr the driving-wheel C, provided with a clutch-disk, F, of a loose clutch-disk, G, provided with lugs h, and a collar,H,provided with inclined guides j,in which the lugs 7i engage, substantially as set forth.

4. The combination,with the driving-wheel C, provided with a elutch-disk, F, of the loose clutch-disk G, a collar, H, connected with the disk G, and provided with a pinion, J, and a reciprocating rackbar, K, engaging with the pinion J, substantially as set forth.

5. The combination,with the driving-wheel C, provided with a clutch-disk, F, of a loose clutch-disk, G, a collar, H, connected with the disk G, and provided with a pinion, J, arackbar, K, engaging with the pinion J, a handlever, N, anda rod, O, connecting the rack-bar with the hand-lever, substantially as set forth.

6. rIhe combination,with a rotary blower, B, of a drivingwheel, C, provided with a clutchdisk, F, a loose clutch-disk, G, and a collar, H, connected with the disk G, and turned alternately backward and forward, substantially as set forth.

7. The combination,with the drivingwheel C, provided with a clutch-disk, F, of a loose clutch-disk, G, a collar, H, provided with a pinion, J, a rack-bar, K, and a casing, L, inclosing the rack-bar and provided with guides Z, substantially as set forth.

8. The combination, with the wheel G, cast with a neck, E, and clutch-disk F, of the loose clutch-disk G, made in halves and mounted on the neck E by securing the halves together, substantially as set forth.

W'itness my hand this 22d day of October, 1885.
